WIRE-TIE-TWISTING DEVICE.

Be it known that LJOHN E. CORNELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Wire-Tie-Twisting Devices, of which the following is a specification.

ll/iy invention relates to a device for twisting wire ties. Both the device and its use are illustrated in the accompanying drawings whereinv Figure l is a side elevation of thel wire tying device with the tie shown in dotted lines; Fig. 2 is a side elevation of a portion of a modified forni: Figs. 3, 4, and 5 show ties of different lengths; Figs. 6, 7 and 8 are illustrations of uses of a tie of a given length for tying crossed reinforcing concrete rods of diiij'erent thicknesses; Figs. 9, lO and 11 are views of the puckered ends of bags of different thicknesses tied by ties of uniform length.

Like parts are indicated by the same characters in all the iigures.

A is a double spirally threaded rod having the suspending ring B at one end on which the rod is rotatably mounted at C. At the other end of the' rod is a hook D, though i1. the modified form there may be two hooks D3, D1. They are adapted to engage the loops D2 on the ends of the ties E.

F is a stop-block movable along the rod and provided with a set-screw G adaptedto engage any one of the recesses H on the spi` rals so that the stop-block F may be fixed in any desired position.

J is a handle adapted to slide along the rod but provided with two inwardly projecting pins K and L adapted to engage the spirals on the rod so that when the handle is moved 'the rod with its hook or hooks rotates.

M, M are reinforcing concrete rods of a given diameter; M1, M1 a similar arrangement of rods of a larger diameter; M2, M2 a like arrangement of rods of a still larger diameter.

N, N1, and N2 are bags of progressively increasing rize or heaviness of material so as to make bag ends of different sizes to receive the ties.

The recesses H maybe arranged in anyl desired manner and as frequently as may be required along the rod so as to vary the length of the rod by minute increments.

I do not wish to be limited tothe precise and arrangement of y The use and operation of my invention are as follows: lVire ties are used for tying bags, securing bundles of material, attaching at their crossing points the rods which are used for reinforcing concrete and` for other such purposes. The sizes of the loops formed by. such ties therefore greatly differ. In ractice it is common to have tiesof different lengths for each such purpose and each Varying size of securing loop finally to .be formed. In other words, the practice is to vary the length of the ties and use a uniformly operating twisting tool. The,` operator with the tool adapted to make,flet us say, three turns, will apply to a given rod crossing or package a wire tie which when it .has received the number of turns predetermined bythe nature of the tool, will produce a tying loop of the right size. When he passes to the next assembly of parts to be secured ii of a different size, he will select the proper tie of a diierent length. By my invention the tool is itself made adjustable as same length of wire tie can be used if the tool be adjusted to make, for example, 'three turns. The result is that I greatly reduce the number of sizes or lengths of ties, and

If now the parts be.. 'I l larger as in the case of reinforcing rods, thel indeed a single length of tie could be used practically for all purposes within the range of ordinary experience. met by the adjustment of the tool. is illustrated in*` the the arrangementgis equally applicable to a single hook tool ora dou-ble hook tool. The latter when used twists the wires as indicated in Fig. 2.

I claim:

1. A tool for twisting wire ties, compris.

ing a rod having a spiral groove thcrealong, a hook at one end, a suspending deviceV at the other, astop adiustably xable along the grooved portion of the rod, and a slidable handle between the hook and the stop with means to engage the spiriti groove.

The condition is- I All thisseveral drawings, and
